Merge patch series "UART support for higher baudrate"
Gokul Praveen <[email protected]> says:
The OMAP specific UART driver is changed from a generic implementation of
certain ops functions to an OMAP specific implementation of it to add
support for higher baudrates for OMAP devices.
Hence to support the above change, static functionality of ops functions
in generic ns16550 UART U-Boot driver is removed and also migrated certain
macros to its header file for usage in device-specific drivers.
